biopsykit.signals.ecg.preprocessing package¶

Module for ECG preprocessing functions.

class biopsykit.signals.ecg.preprocessing.BaseEcgPreprocessing[source]¶

Bases: Algorithm

Base class for ECG preprocessing algorithms.

ecg_clean_: DataFrame¶

clean(*, ecg, sampling_rate_hz)[source]¶

Clean ECG signal.

This is an abstract method that needs to be implemented in a subclass.

Parameters

ecg (DataFrame) – ECG signal
sampling_rate_hz (float) – Sampling rate of ECG signal in Hz

Return type

self

Raises

NotImplementedError – If this method is called from the base class

class biopsykit.signals.ecg.preprocessing.EcgPreprocessingNeurokit(*, method='biosppy')[source]¶

Bases: BaseEcgPreprocessing

Initialize EcgPreprocessingNeurokit instance.

Parameters

method (str, optional) –

Cleaning method to use. Options are:

”biosppy” (the default): Use the preprocessing parameters provided by

biosppy library for cleaning. It uses an FIR filter with cut-off frequencies of [0.67, 45] Hz and order = 1.5 * sampling_rate. * “neurokit”: Use the NeuroKit2 library for cleaning.

PRPROCESSING_METHODS: ClassVar[list[str]] = ['biosppy', 'neurokit']¶

method: str¶

clean(*, ecg, sampling_rate_hz)[source]¶

Clean ECG signal using ecg_clean().

Parameters

ecg (DataFrame) – ECG signal
sampling_rate_hz (int) – Sampling rate of the ECG signal in Hz

Return type

self

Raises

ValueError – If the specified method is not implemented yet
